That's not a counterargument: it's an ad hominem.
At no point in his video does Benn claim to be representing the consensus. The whole premise of his videos is that he is introducing something for which there is very little consensus! Each paper has its own conclusions, which don't have to be the same as Benn's. This whole thing boils down to an attack on Benn's character ability to draw meaningful conclusions on his own.
I am not.
Benn claims that the papers say one thing when in fact, if you read them (even the abstracts), they mostly say the exact opposite. It's that simple.
